LC to LC Duplex Armored Fiber Patch Cable, OS2, Riser (OFCR)

This duplex armored patch cable pairs two LC UPC connectors on an OS2 9/125µm single-mode assembly protected by a helical stainless steel tube. The 3.0mm riser-rated (OFCR) jacket keeps the cable flexible enough for cabinet and under-floor routing while the steel armor absorbs crushing, pulling and rodent damage that would interrupt an ordinary patch cord. G.657.A1 bend-insensitive glass keeps attenuation stable even where the pathway turns tightly around trays and rack posts.

Product Highlights

• LC UPC to LC UPC duplex, OS2 9/125µm single mode
• Helical stainless steel armor against crush, impact and rodents
• G.657.A1 bend-insensitive fiber, 10/5D dynamic/static bend radius
• Riser (OFCR) flame rating for vertical building pathways
• Insertion loss ≤0.3dB, return loss ≥50dB
• Stock lengths 1m to 30m; custom lengths and jackets on request

Conventional patch cords depend on the surrounding duct or tray for mechanical protection. Where cables cross open floors, shared ceilings or industrial spaces, that protection is not always available. The helical steel tube inside this assembly wraps the buffered fibers directly, so the cable itself carries the crush and rodent resistance. Installers can route it through areas that would otherwise require metal conduit, which reduces both material cost and installation time while keeping the pathway smaller and easier to reconfigure later.

OS2 glass at 1310/1550nm supports the long-reach single-mode optics used in campus backbones, carrier access networks and data center interconnects. The duplex LC interface is the standard connection for SFP, SFP+, SFP28, QSFP+ and QSFP28 transceivers, so one cable family covers links from 1G through 100G and beyond. G.657.A1 bend tolerance is fully compatible with legacy G.652.D plant, which means the cable can be mixed into existing single-mode infrastructure without changing loss budgets.

OFCR stands for optical fiber conductive riser: a riser-rated cable whose metallic armor makes it conductive under building codes. The riser rating permits vertical runs between floors in shafts and riser closets. Where the pathway passes through air-handling spaces, a plenum (OFNP) version should be selected instead; where low smoke and zero halogen are specified, the LSZH variant of this same LC-LC construction is available. Matching the jacket to the building section is part of the ordering discussion, not an afterthought.

Standard lengths are stocked for fast delivery: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft), covering the common rack-to-rack and rack-to-frame connections in equipment rooms and data centers. Custom lengths beyond this range are manufactured to order, and the same construction can also be supplied with black or white jackets, APC polish, or alternative connectors through the customized duplex armored cable program. Specifying the exact route length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short, so if your link falls between two stock sizes, simply tell us the distance and we build to it.

Every assembly is terminated with precision zirconia ferrule connectors and measured for insertion loss and return loss before packing. The 0.3dB insertion loss ceiling and 50dB minimum return loss are verified values, not design targets. End-face geometry is checked to keep the physical contact consistent across repeat mating, and the ferrules are rated for up to one thousand insertion cycles, which matters in patching fields that are reconfigured frequently.

Refer to the LC-LC OS2 duplex armored family when requesting a quotation and state the route length, jacket rating and connector polish required. For non-standard combinations of length, color, connector or jacket, send the requirement with the enquiry and the factory will confirm the manufacturable specification before production.
